Multiple device solutions

I'm either doing something wrong or the tapatalk search function doesn't work b/c no matter how I phrase it, I get a "no topic" response.

I'm interested in solutions you guys have found for mounting multiple devices in your trucks/vehicles. I'm looking to mount my GPS, cell phone and a mini-tablet to include an option to power them (a 3-outlet unit I can then plug into the cigarette lighter).

Here's the thing, though. I need to be able to swap the whole assembly as quickly and easily as possible into a vehicle that isn't mine.

Any thoughts would be appreciated. Thanks in advance.
